Manufacturing Quality Control of (DHQD)2PHAL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents remaining from synthesis or purification. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C, expressed as percentage weight loss. |
| Optical Rotation | [alpha]D Measurement | Determination of specific rotation using sodium D-line light source in a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing the temperature range at which solid-to-liquid phase change occurs under controlled heating. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed particle size distribution based on angular scattering pattern of laser light. |
| Microbial Limits | Membrane Filtration | Quantitative enumeration of aerobic microorganisms and absence testing for specified pathogens per pharmacopeial guidelines. |
